Through the application of edge detection procedures to an image, the amount of data to be processed can be considerably reduced by filtering out and discarding information that are of less significance, and retaining the essential structural properties of the image. There are several techniques for detecting and processing image edge. The choice of any method relies on need of the end application. In some cases more than one technique is required to meet a targeted image processing output. The purpose of this paper is to comparatively introduce the basic edge detection methodologies by making analysis of their respective concepts and observing their tradeoffs in some conditions so that decision making criteria are established for guidance in application developments.
